VENEER PACKAGE MACHINE;

SPECIFICATION forming part of Letters Patent No. 744,876, dated November 24, 1903.

Application filed January 2. 1903.

To all whom it may concern:

Be it known that I, WILLARD J. OTT, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Veneer-Package Machines, of which the followingis a specification.

My invention relates to veneer-packagel0 forming machines in which the veneering is wound upon a collapsible drum coacting with an outer compression-roller.

The main objects of my invention are to provide a machine of this class with an improved structure of presser mechanism for holding the veneering upon the drum while same is being wound and for holding its overlapping edges in position to be readily secured together by means of suitable fastenzo ers and to provide an improved connection between the presserroll and presser-bar whereby the latter is carried up and down with the presser-roll in addition to being movable relatively of said roll. I accomplish these objects by the structure shown in the accompanying drawings, in which- Figure 1 is a front elevation of a machine constructed according to my invention. Fig. 2 is a vertical section of the same along the line 2 2 of Fig. 1. Fig. 3 is a top plan of a clamping member adapted for securing veneering to the revoluble drum. Fig. 4. is a side elevation of the same. Figs. 5, 6, 7, and 8 are detail views of the lugs to which the clamping member shown in Figs. 3 and 4 is secured. Fig. 9 is a top plan of one of the hoop-guides. Fig. 10 is a transverse section, partly broken away, of a veneer-package of the type which is to be made by the machine herein described. Fig. 11 is a perspective view of a veneer-package formed from a single sheet of veneering and having its overlapping edges secured' by a metallic fastening-strip.

In the construction shown the drum-shaft 1 is journaled in one end of the members 3 and 4 ot' the supporting-frame and is supported near its other end by a bearing 5 in the gate 6, which is hinged to one of the members 7 of the supporting-frame. A collapsible each other.

is secured to one end of the drum 8.

cross-head 28.

drum 8 is keyed to the shaft 1. The drum 8 Serial No. 137,511. (No model.)

consists of two semicylindrical sections 9 and 10, hinged together at 11, the part 9 being secured to the shaft 1 and the part 10 being movable about the hinge 11. A spring 12 normally urges the two parts 9 and 10 toward The cam 13 is pivoted to the part 10 and is adapted to bear upon the lug 14: of the part 9. As shown in Fig. 2, the drum is expanded so that its periphery is in the form of a true cylindrical surface.

The package-forming material is secured to the drum 8 by means of the clamping member 15, which consists of the bar 16, which is somewhat longer than the drum 8 and which is movably secured to the part 9 of the drum 8. Tapped into one'end of the bar 16 is a bolt 17, which engages a slotted lug 18, which A similar lug 19 is secured to the other end of the drum 8 at apoint directly opposite to the lug 18. The lug 18 is provided with a slot 20, and the lug 19 is provided with a similar slot 2].. The inner face of the lug 19 is beveled, as shown, to form the wedge-shaped cam 22. A bolt 23 is pivoted at 24 to the bar 16 and engages the screw-threaded cam 25, which is adapted to coact with the cam 22 on the lug 19, and thereby draw the bar 16 toward the drum 8.

The members 7 are preferably curved, as shown, to permit the removal endwise of a package from the drum 8. The upper parts 26 are provided with verticallyextending ways 27, within which is slidably mounted a A roller 29 is journaled in the cross-head 28 and is disposed in parallel relation to the drum 8. Springs 30, seated in each of the ways 27 and bearing upon the cross-head 28 and the cross-bar 31 of the supporting-frame, normally urge the roller 29 against the drum 8. Adjusting-screws 32 are provided for varying the tension of the springs 30. Downward movement of the compres sion-roller is limited by means of the stops 33, which engage the pins 34 on the members 7.

A shaft 35 is secured against rotation in the depending arms 36, which are in turn secured to the members 7 of the frame. The hoopguides, which consist of pairs of angle-pieces 37, are mounted upon the shaft 35 and are adjustable to any angular inclination and also to any position along the shaft 35. The anglepieces 37 are secured against movement on the shaft 35 by means of set-screws 38, and the members of each pair of angle-pieces are kept v in alinement by means of a bar 39, which is rigidly secured to the other by means of the set-screws 40.

Power is transmitted to the machine by a belt engaging the pulley 41, which is mounted on a shaft 42 and which connects with the main shaft 1 by means of the friction-wheels 43 and 44, the shaft 45, and the gears 46 and 47 in the order mentioned. The shaft 45 is journaled in fixed hearings in the members 3 and 4 of the frame. The shaft 42 is mounted in pivoted bearings 48, one of which is secured to the member 4 and the other of which is secured to the horizontal bar 49. The bar 49 is provided with vertically-disposed slots 50, at which it is bolted to the member 3 of the supporting-frame. A lever 51 is provided at each side of the bed-plate 52 of the supporting-frame and is fulcrumed thereto at 53. Each end of the bar 49 is provided with an upright 54, which engages one end of one of the levers 51. The other end of each of the levers 51 is normally raised by the spring 55, and the weight of the shaft 42 and its connecting parts normally holds the frictionwheels 43 and 44 out of contact with each other.

A shaft 56 is journaled in the lower part of the frame and has secured thereto a pair of arms 57, to which is journaled a shaft 58. Keyed to the shaft 58 is a pulley 59, which connects with a belt and shafting (not shown in the drawings) and by means of which power is supplied to the shaft 58. The shaft 58 carries at each end a circular saw 60. lever 61 is keyed to the shaft 56 and provides means whereby the shaft 56 may be rocked on its axis. The counterweight 62 serves to balance the saws and their driving mechanism.

For the purpose of facilitating the manufacture of packages from a single sheet of veneering the presser-bar 71 is provided. The bar 71 extends parallel with the presser-roller 29 and is rigidly secured to a pair of vertical rods 72, which are slidably mounted in guides 73 upon the cross-head 28. Each of the rods 72 has mounted thereon above the cross-head 28 a spiral spring 74, which bears between an adjusting-nut 75 and the guide 73 and normally urges the presser-bar 71 upward. A cam 76 is pivoted on the cross-head 28 at 77 and engages the upwardly-extending arm 78 of the presser-bar 71. The cam 76 is provided with a handle 79. The cam 76 is also provided with a shoulder 80, which limits the downward movement of the presser-bar 71 relatively of the presser-roller 29.

The drum 8 is provided with a recess 81, extending longitudinally of same and adapted to receive the edge of a sheet of veneering.

The operation of the device shownis as follows: Assume that the drumis expanded, as shown in Fig. 2, and that the clamping member 16 has been previously removed. Assume also that the handle 79 has been turned to the rightthat is, in the direction of the arrow 82-and that the springs 74have raised the presser-bar upward from the position shown and out of the way. To make a veneer-package such as shown in Fig. 11 from a single sheet of veneering, one edge of the sheet of veneering, being the edge 83 of Fig. 11, is inserted into the recess 81, and the drum is revolved. To start the revolution of the drum, one of the levers 51 is forced down by the foot of the operator. This brings the friction-wheels 43 and 44 into contact with each other, and thus causes the revolution of the shaft 1, with its drum 8. The sheets of veneering are preferably cut to the proper lengths before being wound about the drum, and it is now only necessary for the operator to stop the revolution of the drum as the rear edge 84 of the sheet arrives at a position near the presser-bar 71. The handle 79 of the cam 76 is now thrown to the position shown in Fig. 11, whereupon the presser-bar 71 will be forced downward, so as to hold the rear edge 84 of the veneering into close contact with the part below same. The presser-bar 71 is caused to grip the sheet of veneering at a point slightly in advance of the rear edge 84, so that the operator may now attach a metal fastening-strip 85 in the position shown in Fig. 11.

I11 making double-stave veneer-packages the staves or layers of veneering are fed between the drum and suitable stiffening-hoops. In this case the angle-pieces 37 of the hoopguides are adjusted to con form with the width and desired location of the stiffening-hoops of the veneer-package. Material for stiffening-hoops is passed through each pair of the angle-pieces 37, and two layers of staves are fed alternately between the compressionroller 29 and the periphery of the drum 8. The relative position of the layers of staves and hoops is shown in Fig. 10, in which 63 and 64 are respectively the inner and outer layers of staves. The joints between the staves in the inner and outer layers are staggered, as shown in Fig. 10. While the material is being fed the drum will be caused to revolve, as before described. As soon as a sufficient length of veneering has passed the compression-roller 29 pressure is released from the lever 51 and the drum 8 stops. The clamping member 15 is now secured over the veneering by bringing the bolt 17 into engagement with the lug 18 and swinging the bolt 23, together with the cam 25, into engagement with the lug 19. The length of the bolts 17 and the position of the cam 25 on the bolt 23 having been previously adjusted, a half a turn of the cam 25 tightlyclamps the bar 16 and secures the veneering against the drum 8. It is preferable to clamp the bar 16 into such position, that the veneering projects somewhat beyond the beveled edge 66 of the bar 16. The revolution of the drum is now again started, as before described. When the clamping-bar 16 has arrived at a position at the front of the compression-roller 29, the end of the veneering extending beyond the clamping-bar will have passed under the compression-roller 29. The rotation of the drum is now stopped and the bar 16 is removed. The overlapping ends 67 of the hoop 65 are Wrapped with sheet metal 68 and securely nailed in place, as indicated at 69 in Fig. 10. Before nailing the ends of the hoops the same may also be held in place by means of the presser-bar '7 l. The presser-bar 71 will now be raised to permit the drum to be turned at intervals. The hoops 65 will now be nailed at intervals around the drum, so as to properly secure all of the staves. The drum is now collapsed, and the gate 6 is thrown open to permit the removal of the package toward the right of Fig. 1. The steps 33 prevent the compression-roller 29 from hearing on the package after the drum has been collapsed.

It will be seen that some of the details of the construction shown may be altered with out departing from the spirit of my invention.

such details except as hereinafter limited in the claim.

I therefore do not confine myself to What I claim as my invention, and desire to secure by Letters Patent, is-

In a machine of the type set forth, in combination with a slidably-mounted cross-head, and a supporting means therefor, of springs arranged in said supporting means and engaging said cross-head, means for varying the tension of said springs, a roller journaled in the lower end of said cross-head, a presserbar operating in front of said roller, a pair of rods secured to said presser-bar, projecting through said cross-head and extending above the upper face thereof, nuts arranged on the upper ends of said rods, springs interposed between said nuts and said upper face of the cross-head, a centrally-arranged upwardlyextending arm carried by said presser-bar, a cam carried by said cross-head for engagement with the upper face of said arm, said cam having a handle and being formed with a peripheral shoulder extending transversely of the handle, and adapted to bear against the side of said arm for limiting the movement of the cam, a drum arranged beneath said roller and presser-bar, and means for operating the same.
